Answer:
Pulmonary blood vessel
Explanation:
The pulmonary blood vessel carries low oxygen blood to the lungs and brings high oxygen blood back to the heart.
More specifically, the pulmonary artery carries low-oxygen blood to the lung from the right ventricle of the heart. The blood becomes oxygenated in the lung and the oxygen-rich blood is taken back to the left atrium of the heart by the pulmonary vein.

Cross two heterozygous black mice and tell the possible phenotypes and
genotypes in their offspring.
Answer:
Phenotype: 3 black mice: 1 brown mice
Genotype: 1 BB: 2Bb: 1bb
Explanation:
This question involves a single gene coding for fur color in mice. The allele for black color (B) is dominant over the allele for brown mice (b). This means that a mouse that is heterozygous will be black.
If two heterozygous black parents are crossed i.e Bb × Bb, the gametes produced by each parent are: B and b. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
BB, Bb, Bb, and bb
- The phenotypes of this cross is 3 black mice: 1 brown mice
- The genotypes of the cross is 1 BB: 2Bb: 1bb

James examines a cell from an aloe plant and a cell from an owl feather. Which structure is found only in the cell from the aloe plant?
O A. chloroplast
OB. membrane
O C. mitochondrion
O D. nucleus
The chloroplast will only be found inside the Aloy plant while other structures will be shared by both cells. Option A is correct.
Difference between Plant and animal cells:Both plant cell animal cells are eukaryotic cells, but both have some unique structures.Plants have a cell wall but animals just have a cell membrane.A plant cell has a chloroplast for photosynthesis while an animal cell does not have a chloroplast.Since owl is an animal and Aloy is a plant
Therefore, the chloroplast will only be found inside the Aloy plant while other structures will be shared by both cells.

Which sediment would have the slowest rate of deposition?
a round sediment
O a very large sediment
an irregularly shaped sediment
O a high-density sediment
Answer:
C. An irregularly shaped sediment
Explanation:
Deposition is the settling of sediments within respective basins of deposition.
Irregularly shaped sediments are the slowest to settle within a basin this is due to the frictional resistance of their surface.
As these particles hits the water, the liquid drag on their edges is very great and prevents swift settling.
A. A high density sediment and a large sediment will have a fast settling time.
B. Rounded sediments will impose no friction on the water and they fall through the liquid very fast.
Answer:
the answer is C. an irregulary shaped sediment

how do plants grow helppp
Answer:
During photosynthesis, plants take the water from the soil, and the carbon dioxide from the air, and they make sugars out of it. When plants have the right balance of water, air, sunlight and nutrients, their cells grow and divide, and the whole plant gets bigger and bigger. And that's how plants grow.

Glucose consists of carbon, oxygen and hydrogen atoms. What happens to these atoms
during glycolysis?
a) Nothing, glycolysis does not affect the glucose molecule
b) The atoms are converted into other molecules in a series of chemical reactions
c) The atoms are transformed into energy
d) All atoms are transformed into other atoms in a series of chemical reactions
Answer:
b.
Explanation:
the atoms are converted into other molecules (pyruvate) in a series of chemical reactions
Glucose consists of carbon, oxygen and hydrogen atoms. The thing that happens to these atoms during glycolysi is that The atoms are transformed into energy
Glucose is a type of simple sugar that has six carbon atoms and during glycolysis, is broken down easily because it is a monosaccharide
Glycolysis is the process of breaking down and converting glucose into CH₃COCOOH.
Therefore, what happens to carbon, oxygen and hydrogen atoms during glycolysis is that they are transformed to energy

Why scientific naming is necessary?
Answer:
The correct answer would be - to communicate unambiguously globally.
Explanation:
In different locations on the earth or countries, there are thousands of languages present, and each language has a name for the different species or different organisms that leads to confusion and tough to take the record.
Therefore, there is a two-part scientific name system proposed for every species first name for the genus and second part for the species, it is called "binomial nomenclature." It helps and allows to communicate unambiguously about the species of different organisms globally.
Which object made up of one or more smaller unit objects would make the best model for a group of cells from a plant?
Answer:
D. Dresser
